A table saw includes a base, a work table having a cutting opening, a tank for receiving cooling liquid, a blade partly extending out from the cutting opening, and a guard assembly. The guard assembly includes a guard for covering the blade and for moving upwards under the action of a workpiece. In a working condition, at least a portion of the guard abuts against the workpiece, and the workpiece can slide relative to the guard. The guard has a guiding wall which abuts against the workpiece in the working condition and which guides the cooling liquid into a kerf in the workpiece formed by the blade. The table saw effectively controls the cooling liquid splashed during the cutting operation of the workpiece and prevents the cooling liquid from splashing to dirty the operator, the work table, and the workpiece.

Table saw

A hand-power tool, in particular a drill and/or chiseling hammer, includes a transmission, a machine housing, and an inner housing arranged within the machine housing. The inner housing is provided for at least partially receiving at least one transmission element of the transmission. The at least one transmission element is supported jointly by the inner housing and by the machine housing.

Portable power tool

The disclosure relates to a method of assembling a hand machine tool having (i) an intermediate flange that includes (i) at least one base body having a slot-shaped opening extending in a bearing position and in a bearing, (ii) an intermediate shaft assembly that includes an intermediate shaft and a wobble bearing having a wobble pin, and (iii) a drive piston. The method includes sliding the drive piston onto the wobble pin, introducing the wobble pin into the slot-shaped opening such that the drive piston slides into the at least one base body, and inserting, in an assembly direction corresponding to a direction of a longitudinal axis of the base body, the intermediate shaft of the intermediate shaft assembly into a second base body of the immediate flange.

Method of assembling a hand machine tool

The invention relates to an electrical device, especially an electric tool, which has a motor unit provided with a motor housing, and a receiving unit for receiving at least one drive element. According to the invention, the electrical device includes a motor sleeve for coupling the motor unit to the receiving unit.

Electrical device

The invention relates to a hand-held power tool having a bearing race inserted into a bearing socket. The bearing socket and the bearing race have recessed ring sectors positioned relative to one another in an overlapping manner. The ring sector of the bearing race is configured by breaking out a circumferential section of the bearing race, which is defined by predetermined breaking points.

Hand-held power tool

The invention relates to a system for a hand-held machine tool, particularly a pistol-shaped hand-held machine tool, which includes at least one first auxiliary unit, and a coupling mechanism that is used for coupling the first auxiliary unit and the hand-held machine tool. An example of the invention includes a suction unit as the first auxiliary unit for collecting debris from a hand-held drilling tool. The system also provides for at least one additional auxiliary unit to be coupled to the held-held power tool by the coupling mechanism. An example of the invention includes an illuminating element as an additional auxiliary unit which can be coupled to the tool with the coupling mechanism so as to be interchangeable with the first auxiliary unit.

System with a hand-held power tool

A drill hammer for the three operation modes of drilling, chiseling, and hammer-drilling has a motor with a motor shaft; a gear with an intermediate shaft, a driving gear wheel, a toothed slaving shaft , a shifting hub, and a driven gear wheel; a percussion mechanism with a wobble disk and a wobble gear wheel; and a driven shaft with a driving gear wheel and a drill chuck. The gear is configured to be changed over easily without axial displacement of running gears that mesh with one another so that the drill hammer is more robust, shorter or more compact, and lighter in weight. The drill hammer is thus simply and economically constructed and whose efficiency is not impaired by the gear shifting mechanism.

Drill hammer with three modes of operation

The invention relates to a hand machine tool which has an intermediate flange, particularly for receiving transmission elements. The flange has at least one base body having at least one bearing point. It is proposed that at least one opening is provided at least in the area of the bearing point.

Hand machine tool

An electric hand-held power tool has a housing, a double-shelled handle attached axially to the housing, a selector ring pivotably located in the housing, and an actuating element supported by the selector ring and swivelable manually. The housing and the handle have a line connecting domes oriented parallel to an axis of the housing and located in a parting plane region between the housing and the handle for receiving connecting units. The connecting domes include centering elements for guiding and exactly positioning the handle shells when the handle shells are attached individually to the housing.

Electric hand-held power tool

A very easy-to-actuate, replaceable tool fitting is comprised in that at least one movably supported profiled body () on an output spindle () or on the tool fitting () of the hand-held power tool and at least one profiled recess () on the output spindle () or on the tool fitting () are shaped and situated in such a way that when the tool fitting () is slid onto the output spindle (), the at least one profiled body () engages in detent fashion in the at least one profiled recess (), achieving both an axial locking and a rotary driving of the tool fitting () in relation to the output spindle () and means () are provided, which, through a rotating and sliding motion of the tool fitting () on the output spindle (), guide the profiled body () into the profiled recess ().

Hand-held power tool with a replaceable tool fitting

A tool fitting that is provided to accommodate a rotary hammer bit and/or a chisel bit () and an adapter (). The tool fitting has centering elements () for at least reducing the mobility of the adapter () when mounted in comparison to the mobility of the rotary hammer bit and/or chisel bit () when mounted.
